Dealing with unfair ratings in such systems has been recognized as an important but challenging problem. Many unfair rating detection approaches have been developed and evaluated against simple attack models. However, the lack of unfair rating data from real human users and realistic attack behavior models has become an obstacle toward developing reliable rating systems. To solve this problem, we design and launch a rating challenge to collect unfair rating data from real human users. In order to broaden the scope of the data collection, we also develop a comprehensive signai-based unfair rating detection system. Based on the analysis of real attack data, we discover important features in unfair ratings, build models and generator developed in this paper can be directly attack models, and develop an unfair rating generator.
